Abstract: 1,051,807. Electrolytic testing apparatus. BECKMAN INSTRUMENTS Inc. June 4, 1964 [June 4, 1963], No.23125/64. Heading G1N. In an electrochemical cell for polarographic analysis of hydrogen in a gas or liquid sample for the detection of hydrogen leaks or monitoring a nuclear reactor corrosion control system, hydrogen diffuses through a membrane 27 and is oxidized at the anode 21 thereby causing current to flow through the cell. The anode may be platinum, gold or rhodium and its surface 21 may be coated with platinum black or a mixture of platinum black and rhodium. The cathode 23 may be silver coated with silver chloride. The membrane is preferably P.T.F.E. or may be polypropylene or polyethylene. Suitable electrolytes are buffered sodium chloride or potassium chloride solutions which may be treated to discourage growth of algae. An electrical circuit suitable for use with the cell is described with reference to Fig.2 (not shown). Alternatively, the electrodes could be chosen to provide the required potential themselves. Suitable potentials for various electrolytes are exemplified.

The drivers 10 are fastened on a driver-ring 9 screwed to the knife shaft 1, and driving grooves 11 extend axially between the wedgeshaped grooves 8. In operation, in the absence of a sheet to be cut, since no resistance is offered to the oppositely rotated blades, they remain out of or only slightly in contact with each other. When a sheet is introduced, the cutting knife stops because of resistance, the drivers slide along the groove surfaces, and the knife 2 is pressed against knife 4 to effect cutting. The knife 2 may be removed from the bush 5 and replaced by a perforating knife 12, Fig. 2, the drivers 10 being introduced into the grooves 11, with the stop ring 7 fastened directly at the side of the bush 5. In a second embodiment, the cutting-knife is fastened by a threaded ring on a bush mounted on an intermediate bush secured to the knife shaft, and carrying drivers to engage the driving grooves. The device for scoring may be similar to that for perforating and the embodiments may be combined, as desired. The grooves 11 may be disposed on the end face of the supporting bush 5 opposite to the grooves 8, and when changing from cutting to perforating the stop ring 7 may be replaced by the driving-ring 9. When only one incline is used it may be constructed as a coarse screwthread with the pressure member engaging therein.

Abstract: 1,239,126. Photo-electric focusing. NATIONAL RESEARCH DEVELOPMENT CORP. Jan.23, 1967 [Jan.23, 1969], No.3738/69. Heading G1A. The sharpness of focus of an image in a plane is determined by scanning a region of the image by a radiation sensitive device which provides a signal proportional to the intensity of illumination in the scanned region which signal is examined in a detector for the presence of frequency components above a predetermined value. The signal is analyzed in a circuit including an adjustable high pass filter which passes the high frequency components of the signal to an amplifier rectifier and power circuit including a relay which operates to light a lamp when the image is in focus or controls a servo to focus the system. The radiation sensitive device may lie in the plane of the screen or may be a Vidion tube which is focused to receive light reflected from the screen and is connected to an oscillator which provides the line scan. A focused edge of the image will provide a sharp change in the level of intensity as it is scanned whereas an unfocused edge will not provide any such change. The scan may be provided by movement of the image during the pull down period of the projector either by providing a low intensity visable light or an infrared radiation during this period. A negative filter may be provided in the shutter or the projector lamp may be dimmed. In further modifications two devices may be used either in the plane of the screen or spaced in front and behind it to determine the direction of movement of lens 81 to refocus the image. The devices are spaced apart in the plane of the screen and are connected in a differential circuit so that a phase difference is detectable in their outputs when a focused edge is scanned. If the edge is blurred the outputs of the devices will vary together and no difference will be detectable. As shown in Fig.6 devices 70, 71 may be positioned behind the screen 84 which has lenses 72, 73 positioned in its edge such that images are obtained corresponding to distances 10 ft. in front and behind the screen respectively. Each device feeds a filter and the signals after rectification and smoothing feed a differential circuit whose output is zero when the image is in focus. This output feeds motor 8 to adjust lens 81. A third device 82 is provided at the screen to generate a locking. signal when focus is obtained.
